Abstract

A chasing rope light includes a flexible core tube which has a plurality of cavities transversely and spacedly formed thereon, a pair of conductive wires longitudinally extended along the core tube, and a pair of illuminating units. Each of the illuminating units has at least an illuminator and a diode electrically connected together in series and alternately and transversely disposed in said cavities of said core tube respectively for securely holding said illuminators in position. The illuminating units are electrically connected with the conductive wires in parallel such that when a current is applied to the conductive wires, the current is rectified by the diodes so as to alternately pass through the illuminating units for illuminating the illuminators thereof.

Claims

1. A chasing rope light, comprising:

an elongated core tube having a plurality of cavities transversely and spacedly formed thereon;

a first and a second conductive wire are longitudinally extended along said core tube;

a connector means for electrically connecting said conductive wires to a power source;

a first and a second illuminating unit, each comprising a diode and at least an illuminator electrically connected together in series and alternately and transversely disposed in said cavities of said core tube respectively for securely holding said illuminators in position, wherein both first ends of said first and second illuminating units are electrically connected to said first conductive wire in parallel and both second ends of said first and second illuminating units are electrically connected to said second conductive wire in parallel, wherein said diode of said first illuminating unit and said other diode of said second illuminating unit are arranged in opposite direction that when a current is applied to said first and second conductive wires, said first diode of said first illuminating unit enables said current flowing from said first conductive wire to said second conductive wire via said first illuminating unit, and said second diode of said second illuminating unit enables said current flowing from said second conductive wire to said first conductive wire via said second illuminating unit;

a third conductive wire longitudinally extended along said core tube in such a manner that said three conductive wires are evenly provided along said outer circumference of said core tube, and a third illuminating unit connected between said second conductive wire and said third conductive wire, wherein said third illuminating unit comprises one or more illuminators alternately and transversely disposed in said respective cavities of said core tube; and

a fourth illuminating unit connected between said second and third conductive wires, wherein said third illuminating unit further comprises a diode electrically connected with said illuminator of said third illuminating unit in series, and said fourth illuminating unit comprises a diode and at least an illuminator electrically connected together in series, wherein said illuminators and said diodes of said third and fourth illuminating units are also alternately and transversely disposed in said respective cavities of said core tube respectively, wherein both first ends of said third and fourth illuminating units are electrically connected to said second conductive wire in parallel and both second ends of said third and fourth illuminating units are electrically connected to said third conductive wire in parallel, wherein said diode of said third illuminating unit and said diode of said fourth illuminating unit are arranged in opposite direction that when a current is applied to said third and fourth conductive wires, said first diode of said third illuminating unit enables said current flowing from said fourth conductive wire to said third conductive wire via said third illuminating unit, and said diode of said fourth illuminating unit enables said current flowing from said third conductive wire to said fourth conductive wire via said fourth illuminating unit.

2. A chasing rope light, as recited in claim 1, further comprising an outer casing seadedly encircling said outer circumference of said core tube so as to cover said core tube and said first, second and third conductive wires for protecting said chasing rope light.

3. A chasing rope light, as recited in claim 2, wherein said core tube is make of flexible material, and each of said illuminators is a LED.
